NE107 alerts overview
NE107 alert parameters
NE107 has four alert status signals. They are in order from highest to lowest priority:
1. FD_FAIL_ACTIVE
2. FD_OFFSPEC_ACTIVE
3. FD_MAINT_ACTIVE
4. FD_CHECK_ACTIVE
You can configure any of the eight alert conditions to annunciate as any of the four status
signals. You can also map individual alert conditions into multiple status signals.
Alert parameter definitions and factory defaults
Note
All eight alert conditions are factory assigned to appropriate status signals. Change the
parameter assignment of individual alert conditions only if needed.
Devices are shipped from the factory with all applicable alerts enabled. The factory default
alert conditions reported in each status signal are:
1. FD_FAIL_ACTIVE
2. FD_OFFSPEC_ACTIVE
3. FD_MAINT_ACTIVE
4. FD_CHECK_ACTIVE

a. Incompatible module
b. Sensor failure
c. Electronics failure
A FD_FAIL_ACTIVE status signal indicates a failure within a device that will make the
device or some part of the device non-operational. This implies that the process
variable may no longer be available and the device is in need of immediate repair.
a. Pressure out of limits
b. Sensor temperature out of limits
A FD_OFFSPEC_ACTIVE status signal indicates that the device is experiencing
pressure or temperature conditions that are outside the device operating range.
This implies that the process variable may no longer be accurate. It also implies that
if the condition is ignored the device will eventually fail.
a. Display update failure
b. Variation change detected
A FD_MAINT_ACTIVE status signal indicates the device is still functioning but an
abnormal process or device condition exists. The device should be checked to
determine the type of abnormal condition and recommended actions to resolve it.
a. Function check
